According to more scientific projections' accredited renewables as a whole (solar, wind, small and large hydropower, geothermal energy of the sea) in 2050 could meet the full electricity needs of humanity.
would a goal legendary, like the first man to set foot on the moon (he just celebrated the quarentennale), the first aircraft that could be off the ground, or the invention of internet and e-mail messages. In order for this to happen, we need a new industrial revolution: the shift from an economy based on internal combustion engine, typically using fossil fuels to an economy based on the electric motor. Because the cycle is virtuous, of course the energy to run electric motors will be produced from clean renewable sources like solar and wind power. The hydrogen could be an additional clean energy carrier, if produced from renewable sources. Only in this way we can drastically reduce pollution from petroleum products and coal, while reducing environmental damage and health: unfortunately, climate change are a reality with which we deal with today and we should learn to live with.
With the new industrial revolution we have outlined, however, we would be only half done. is not enough to worry about how to produce energy, but we must take to heart even as it consumes .
We can not think that our consumption can grow indefinitely: it is essential to ask how to target their stabilization and then reduction.
This in all sectors: industrial, residential, commercial. We know that one of the tenets of the capitalist economy that is more 'is consumed, more' you create wealth for all, but just a single figure to refute that axiom: for at least a fifth of our electricity consumption, kWh saved through the intervention Energy efficiency is cheaper than that produced and consumed . (Let us pause a moment to reflect on how much energy we waste in every moment of our existence). Today we have all the tools at hand to field the transformation which was mentioned at the beginning: the combustion engine to the electrical system, oil to electricity from 'renewable sources applied in every possible area of \u200b\u200bhuman activity, up to replace even the most 'small gasoline engine, diesel or gas. And development incessant and furious world of the photovoltaic industry, also Italian, makes us believe that this will be the main way to deal with and try to win the environmental, economic and social development of the twenty-first secolo.
